我已经看到类似的错误，但似乎没有任何修复对我有用（我尝试删除所有 .disable 文件，但得到的响应是“没有这样的文件”）
我正在使用安装在供应商提供的服务器上的 Ubuntu 14.04，我有管理员权限。每次我尝试使用apt-get install或apt-get upgrade等时，我都会得到此输出或类似输出，似乎没有任何变化或安装：

我不确定如何或需要更改什么才能使标准 Ubuntu 14.04 apt 包正常运行。
我对 UNIX 故障排除领域还不太熟悉，所以任何帮助都非常感谢！如果您需要任何其他信息，请告诉我。
编辑 1：根据@Jos 的建议，我调用了sudo apt update类似的结果：
Ign file: updates/ InRelease
Ign file: updates/ Release.gpg
Ign file: updates/ Release

我认为这是因为供应商已将机器设置为忽略原始 apt 管理器配置，而倾向于通过他们自己托管的软件包文件获取更新？我不确定如何诊断或修复此问题。
答案1
事实上，这里没有什么问题。
首先，运行sudo apt update以使您的软件包数据库与在线存储库保持同步。
您安装了许多未使用的软件包。它们只是占用空间。使用 删除它们sudo apt autoremove。
您有几个更新需要注意。这些更新将被“保留”，直到您确定要安装它们为止。（这样做通常是安全的。）使用 安装这些更新sudo apt dist-upgrade。
*.USBinstaller删除目录中调用的文件/etc/apt/sources.list.d。使用sudo命令行执行此操作。我不知道这些文件来自哪里，但我很确定您现在不需要它们。不过，这些文件不会导致 apt 进程失败；正如它所说，它们只是被忽略了。
